North Atlantic CTD/STD Profiles from Atlantis II Cruise

High-resolution conductivity-temperature-depth and salinity-temperature-depth profiles collected during the ATLANTIS II research cruise in the North Atlantic Ocean. The dataset was processed by the National Oceanographic Data Center to its F022 standard format. Data collection occurred from October 1979 to August 1981.

Use Cases

• Analyzing vertical profiles of temperature and salinity for water mass identification.
• Calculating density (sigma-t) from measured temperature and conductivity/salinity values.
• Studying temporal changes in oceanographic conditions at specific stations using position, date, and time data.
• Correlating subsurface measurements with reported surface meteorological and sea condition data.

Strengths

• Data provides nearly continuous profiles with depth intervals as fine as 1 meter.
• Records include cruise, instrument, position, date, time, and sampling interval metadata for each station.
• Dataset is processed to a recognized standard (NODC F022 format) ensuring consistency.

Limitations

• Exact row count, column names, and file size are not provided by any source.
• Data.gov lists a 2026 update date, which conflicts with the 1981 collection end date, suggesting possible metadata management artifacts.
